Be, it known that l, lYiLLLiM ERASTUS and State of lllinois. have invented a new and useful Improvement in Corrugatedllate heels, of which the following is a specification.

The object of my invention is to make an automobile wheel of the disk t Y )e that will be ver strong and cheaply made.

The invention is set forth in the claims. Reference will he had to the accompanymgr-drawing, in which Figure l is a front elevation of the wheel.

Figure 2 is e. radial section on a larger scale than that of Figure 1, showing only one-half of the wheel.

Figure 3 is a section on line 33 of Figure 1.

In the drawing 1 indicates the hub of a wheel of the ordinary type for automobile trucks, here shown as being a front wheel. The web of the wheel is made of {i fiat plate disk 2 having, for lateral stiffening purposes, around its eentralopening radial corrugations 3 lying, wholly on one side of the plane of the non-corrugated body. of the disk. At that opening, the disk has marginal notches or punched holes 4 which cut away portions of the general marginal curve. I

The hub iscast-on and the molten metal runs through these holes 1- as is indicated by 5 in igure 3. The metal of the hub is provided with adouble walled ruliled flange 6, which-1 follows the'contour of the corrugations around the hub barrel, and the outline of this double wall flange is shown by Figure 3. I

The trend of the wheel is formed by having the metal of the plate 2 bent forward as is indicated at 7 and then verticall3 as indicated at 8, forming a simulation in appearance to the front edge of a wheel haw mg a. wooden felloe. This metal is then turned over into the rim of the wheel as indicated at 9.

The outer edge 10 ot the (tread portion 9. of the wheel is reinforced by'an angle ringwimmnness'rns witnessesemits, 11mm, ,j, '5

This is {cheap method of'meking' at wheel and it Inakes'a very strong'whee'l. Wu'imms. a citizen of the lg'hited States, a resident of Chicago, in the ohunty of Cook The arrangement of the'plate 2 in the regiioir'of'the rivets 13, where it joins the in side leg: of the angle ring.11,"is iipproxiinatelv in the center plane'of the tread load of the wheel.

The arrangement of this angle rin 11 is such that a stock section of angles may he used, which permits the cheapest type of material to, be furnished for this purpose.

This vert cally arranged le of the angle 11 I indicate at 15, and it is a desidera-tunr to have it in a direct line of the load thrust of the wheel, as I have shown it. i

"as radial corrugations stiffen the inner margfnal portion of the disk which especially needs strength, so corrugating the thin hub flanges adds to their stiffness and to that of the embraced disk. and further, that integrally uniting" these flanges at short intervals, as shown in Figs. 2 and 3, makes them mutually supporting whereby this most heavily strained portion of the wheel resists any side thrust insufiicient to bend at once the three corrugated members. which are virtually one member having a broad base at the periphery of the hub proper, or hub body.

lVhat I claim is:

1. The combination with a single disk wheel having one disk face in aplane parallel to the general plane of the 116.1 with its central zone pressed outward on one side from'said plane to form corrugations entending from the medial zone of the disk nearly to the corresponding end of the hub to brace the disk and stiffen the hub, said hub having wide, thin serpentine cast-on I flanges. whereby a thin walled hub has its J land having its we where it joins the felloe region, in a close approximation to the center loadline of the wheel, and with srein n forcing angle having aivertioally arranged: flange supporting a part of the rim portion inward into the vertically arranged zone of the plate.

.3. In a wheel of the class described, sf;

plate-dished togive stiffness and corrugated where it: {oinsthe hub for the purpose of aiding in ate'ral stifiness and with a smooth ,zonejwhere itjoins the felloc' regions and "with a boxed-in rim portion produced by drawing the plate forward corrugated zone and a central zone with deep radial corrugations formed on one side of the plane of the outer zone combined with a cast-on hub lying in the central opening of the disk and having two circumferential flanges corrugated like the inner margin of the disk and rigidly holding the marginal portion between them.
